When an object moves faster than sound, it creates an ultrasonic explosion. Therefore, in theory, if something moves faster than light, it will also produce a fruit

Chinese scientists claim to have found important evidence for the hypothesis that gravity moves at the speed of light, based on data collected from the tide.

Single photon cannot pass the speed of light, just like Einstein's theory. Hoping to go through time is mentioned about 10 years ago, when scientists discovered ...

A new study says that the events that Einstein calls
